-2 1/4 = -9/4
(-9/4)/(-2/3)
Step-by-step explanation:
Y=1/3-3/1
-x+1= 1/3-3/1
= -3+1
= -2.
You move the decimal point forward until it reaches the one so it looks like this:
1.4 x 10⁵
the exponent, 5, just tells you how many spaces the decimal point moved.
To solve, you first want to find the total she hiked in the morning. 1.75+2.4=4.15. Then, you want to subtact the total miles she hiked in the morning from the total miles she hiked in total. 6.5-4.15=2.35. The last step is to compare the miles hiked in the morning compared to the miles in the afternoon by finding the difference. 4.15-2.35=1.8, so therefore she hiked 1.8 more miles in the morning than in the afternoon,
